Below is the information needed for auditing success and failure logon events in an ADFS Server Farm (Check out our Identity Cloud Solutions for additional consulting help)
Configure ADFS Event Logging
You can configure event logging on federation servers, federation server proxies, and Web servers. ADFS events are logged in the Application event log and the Security event log.
You must turn on audit object access at each of the federation servers, for ADFS-related audits to appear in the Security log. This will allow the Federation Service to log either success or failure errors. For more information about how to turn on audit object access, see Audit object access (https://go.microsoft.com/fwlink/?LinkId=62686).
